Definitions

  • the present invention relates to a winding operation control method and apparatus for an automatic winder provided with rows of a multitude of spindles of a winding unit for taking up the yarn to produce a package.
  • a yarn supply bobbin produced at a fine spinning frame such as a ring spinning frame is supplied to an automatic winder of the following process, where the yarn is unwound, being taken up onto a package to a specific amount of yarn and a specific shape while yarn faults are removed.
  • an automatic winder of the following process, where the yarn is unwound, being taken up onto a package to a specific amount of yarn and a specific shape while yarn faults are removed.
  • Usually several to scores of yarn supply bobbins are used to produce one package.
  • this automatic winder winding units having a multitude of spindles are arranged in parallel. Hereinafter the arrangement of one winding unit U will be explained by referring to FIG. 5.
  • the yarn Y unwound from a yarn supply bobbin 1 flows through a balloon breaker 2, an optical feeler 3 for detecting the presence or absence of the yarn Y, a disc-type tensioning device 5 for manual adjustment, and a yarn fault detecting head for checking and cutting off a yarn fault at a clearer 6, being taken up onto a package P rotating on a traverse drum 7.
  • This package P is rotatably supported on a cradle 9 at both ends of its taken-up tube 8.
  • a friction roller 10 which is slightly larger in diameter than the large-diameter end of the take-up tube 8; at the initial period of winding on the package P the friction roller 10 and the drum 7 rotate in contact with each other, taking up the yarn Y.
  • a yarn signal from the clearer 6 is inputted into a unit controller 11.
  • the unit controller 11 is designed to cut off and remove a faulty yarn by the cutter built in the clearer 6 upon finding out the faulty yarn such as a slub, thick yarn and thin yarn.
  • the suction mouth 13 is rotated to the package P side and at the same time the drum 7 is rotated reversely to catch the upper yarn, then rotating the suction mouth 13 downwardly in the drawing to guide the upper yarn to the yarn joining device 15.
  • an intermediate joining pipe 14 is rotated to the vicinity of the feeler 3 to catch the lower yarn running to the feeler 3; then the intermediate joining pipe 14 is rotated upwardly in the drawing to guide the lower yarn to the yarn joining device 15.
  • the drum 7 is rotated to restart winding.
  • a motor 16 which drives the drum 7 is controlled by the unit controller 11.
  • the rotation of the drum 7 is detected by a drum rotation sensor 17, which produces pulse signals which are counted and integrated by the unit controller 11.
  • An integrated value thus gained is compared with a set value by a control device 18 which controls the winding unit U of a multitude of spindles.
  • the feeler 3 functions to detect the absence of the yarn, outputting a no-yarn signal to the unit controller 11.
  • the feeler 3 When the bobbin 1 has been fully unwound, the feeler 3 outputs the no-yarn signal and at the same time the clearer 6 which detects a yarn defect stops outputting a yarn signal.
  • the unit controller 11 With the detection of the empty bobbin, the unit controller 11 outputs a "bobbin change" command; the empty bobbin is thus discharged and a new bobbin 1 is fed to the winding position.
  • the yarn end found out from the new bobbin 1 is blown upwardly to the vicinity of the feeler 3, being joined at the yarn joining device 15 by the operation of the above-described suction mouth 13 and the intermediate joining pipe 14. Subsequently the unwinding of the bobbin 1 is started.
  • each winding unit usually several to several tens of supply bobbins 1 are joined while being removed of their yarn defects, forming one full package.
  • Production performance of this winding unit U largely depends upon the winding speed, but the practical winding speed of a prior-art winding unit U was around 1000 m/min. because the unwinding tension increased with an increase in the winding speed.
  • the mean angle of separation of a yarn from the yarn layer of the bobbin 1 decreases, resulting in friction between yarns or friction between the yarn and the take-up tube and sudden increase in the unwinding tension which causes the occurrence of yarn breakage due to the tension.
  • the winding unit U is provided with equipment along the yarn path and there exists almost no excess space for newly setting up a yarn tension detecting device.
  • the tension detecting device is comparatively expensive and therefore it is impossible to set it for every winding unit U. It is, therefore, considered to output a desired tension pattern to the variably controllable tensioning device 5 of each winding unit U from the control device which controls the winding unit U, without providing the tension detecting device.
  • the tension adjusting effect of the tensioning device varies with the type of yarn to be handled, it is unknown whether the yarn tension is gradually decreased for the purpose of actually offsetting an increased unwinding tension when a tension pattern one-sidely set by the control device 18 is used.
  • the present invention has been accomplished and has an object to provide a tension control device of an automatic winder capable of increasing and decreasing the yarn tension to a desired value without using a tension detecting device at each winding unit.
  • a tension control device of an automatic winder is equipped with a variably controllable tensioning device for each of a multitude of spindles of a winding unit; a yarn tension detecting device for specific one of the multitude of spindles; this yarn tension detecting device serving to control the yarn tensioning device for the specific spindles; and a control device for controlling the yarn tensioning device for a multitude of other spindles on the basis of an output value of the tensioning device for the specific spindles.
  • the winding unit functions commonly to unwind yarn-supply bobbins of the same type of yarn by all or a group of many spindles; therefore the yarn tension detecting device is provided for specific one of the multitude of spindles; the specific spindles are controlled to gain a desired yarn tension; and furthermore the tensioning device for a multitude of other spindles is controlled on the basis of output to the tensioning device for the specific spindles, thus obtaining a desired tension pattern for the multitude of other spindles as the specific spindles.

  • the unit controller 11 for others than the specific spindles differs also in that it is fitted with the output circuit 11a correspondingly to the tensioning device 20 and the ratio output circuit 11c correspondingly to the output circuit 11a. Other differences are similar to those shown in FIG. 5, wherein the same reference numerals are used to omit its explanation.
  • the output circuit 11b of the yarn tension detecting device 30 outputs a signal corresponding to an actual tension value to the feedback circuit 18a, through which the yarn tension is controlled to a desired tension, and then the reference voltage (corresponding to the torque) T2 is outputted to the tensioning device 20 through the output circuit 11a.
  • the feedback circuit 18a is not constantly operating as described above, but operates only during a specific period of winding for package formation, feeding back the actual tension value of the specific spindle and the set tension value to thereby adjust the reference voltage at which a desired tension is obtainable.
  • the reference value output circuit 18b outputs the reference voltage in relation with the set tension value thus fed back, to the output circuit 11a of other spindles than the specific spindles, and other multitude of spindles operate the tensioning device similarly to the specific spindles.
  • the ratio output circuit 11c provided at the unit controller 11 of each spindle serves to change the tension value corresponding to the take-up condition of each spindle by use of the ratios R1 and R2 in relation to the reference voltage.
  • the tensioning device 20 has a pair of first comb-shaped part 21 and second comb-shaped part 22 which can be engaged with each other.
  • Either of the comb-shaped parts 21 and 22 has three teeth 23 or 24 which are equally spaced, protruding sidewards, so that these combs may be engaged with each other.
  • the first comb-shaped part 21 is secured by bolts to a bracket 25, which is secured on the side face of a tenser box not illustrated.
  • the second comb-shaped part 22 is also secured by bolts to a rocking lever 26 (or bracket 26) and is rotatable around the axis X--X.

  • To an arm 26a provided on the opposite side of the rocking lever 26 is attached a connecting rod 27, the forward end of which is inserted on an eccentric shaft 28a of an eccentric lever 28.
  • the eccentric lever 28 is connected to a rotary-type solenoid 29.
  • This solenoid 29 is designed to operate a moving iron by utilizing magnetic attraction obtained by supplying the current to the coil, thereby outputting a turning torque correspondingly to the voltage applied.
  • the combs 23 and 24 are curved in a crescent form in the tooth part for the purpose of holding the yarn Y in the yarn path.
  • the teeth of the movable comb 23 are inserted for engagement with those of the secured comb 24 as shown in FIG. 3(a). When these combs are in engagement, the yarn Y, therefore, is bent zigzag.
  • the degree of engagement of these comb 23 and 24 depends upon the rocking torque of the rocking lever 26 produced from the solenoid 29, being easily adjustable by controlling the voltage to be applied to the solenoid 29.
  • the solenoid 29 turns the eccentric lever 28 in the direction 1, actuating the rocking lever 26 in the direction 3 through the connecting rod 27 to open the comb-shaped parts 21 and 22.
  • the yarn is passed or joined.
  • the solenoid 29 rotates the eccentric lever 28 in the direction 2, to thereby rock the rocking lever 26 in the direction 4 through the connecting rod 27, thus closing the comb-shaped parts 21 and 22 into engagement with each other as shown in FIG. 3(a).
  • the yarn is bent zigzag, and adding a yarn tension according to the degree of bend.
  • the degree of engagement of the combs 23 and 24 decreases, thus lessening the yarn tension.
  • the degree of engagement of the combs 23 and 24 increases in accordance with an increase in the yarn tension, increasing the yarn tension.
  • the gate-type tensioning device 20, as described above, has a good response, functioning to compensate for peak increase and decrease of the yarn tension.
  • the tensioning device described above is provided for every spindle and is operated by means of the unit controller 11. Then, the control device 18 outputs set values which are specific tension patterns described later, to all machine frames for forming the same type of package or the unit controller 11 of one group of winding units.
  • the solenoid 29 adjusts the amount of engagement of the combs 23 and 24 through the unit controller 11 to adjust the yarn tension, thereby presenting a specific tension pattern.
  • the tension detecting device 30 is installed for all machine frames for forming the same type of package or a specific winding unit (a representative spindle) of one group of winding units.
  • This tension detecting device 30 is constituted of an angle sensor which detects the angle of rotation of the axis X--X of the lever 26 (or bracket 26). The principle of yarn detection by this angle sensor will be explained by referring to FIGS. 4a and 4b.

  • the displacement between the combs 23 and 4 increases to ⁇ 2 for balancing.
  • the displacement ⁇ and the yarn tension T has a specific relationship with a known torque F. Therefore, there is predetermined by experiments a relational expression of the yarn tension T, the displacement ⁇ and the torque F; and using this relational expression the yarn tension T is calculated out from the yarn tension T, the displacement ⁇ and the torque F.
  • the above-described gate-type tensioning device is desirable as an adjustable tensioning device 20; in this case, a disc-type tensioning device may be used in which the yarn is passed between two discs pressed with a pressure against each other and the pressure is variably controllable.
  • the yarn tension detecting device 30 is preferably built in the tensioning device 20, but if there exists an excess space in the yarn path of the winding unit, a unit-type tension sensor having a movable rod placed between two fixed rods may be separately installed so as to measure the yarn tension by utilizing a pressure of the running yarn acting on the movable rod.
  • the unwinding assisting device 35 of FIG. 1 will be explained.
  • This unwinding assisting device 35 properly restricts ballooning of the yarn being unwound from the bobbin 1 in order to suppress the change and increase of the unwinding tension, and is preferably used together to narrow the range of adjustment of the above-described tensioning device 20.
  • the unwinding assisting device 35 shown in the drawing consists of a fixed cylinder 36, a throttle 37 in the fixed cylinder 36, a movable cylinder 38 inserted over the fixed cylinder 36, a lifting device 39 vertically movably supporting the movable cylinder 38, and a sensor 40 mounted at the lifting device 39 for detecting the chess section 1a.
  • the spacing between the sensor 40 and the chess section 1a becomes wider, so that the unit controller 11 inputted with a signal from the sensor 40 will actuate the lifting device 39 to lower the movable cylinder 38, thus maintaining a nearly fixed spacing between the movable cylinder 38 and the chess section 1a and further keeping a proper unwinding angle of the yarn which tends to balloon after being unwound from the chess section 1a.
  • the fixed cylinder 36 and its throttle 37 serve to suppress balloon variation of the yarn reaching the feeler 3. The variation and increase of the unwinding tension can be lessened by thus properly maintaining the shape of the balloon.
  • this unwinding assisting device 35 has been set in the vicinity of a 30-percent wound bobbin (about 30 percent of yarn remaining on the bobbin) where the unwinding of the yarn from the chess section 1a tends to be disturbed.
  • the location of this 30-percent wound bobbin can be detected by an electronic scale or other mounted at the lifting device 39.
  • FIG. 2 At the time t1 the doffing has been completed, an empty take-up tube 8 has been mounted on the cradle 9 in FIG. 1, and the friction roller 10 is in contact with the drum 7. In this state the yarn wound on the take-up tube 8 is not in contact with the drum 7, and therefore, a slightly high yarn tension T1 is used until a 2 to 3 mm thick yarn layer is formed, and at the time t2 the yarn tension is changed back to the specific yarn tension T2.
  • the yarn tension is changed to the slightly high yarn tension T1 to prevent slough-off during a period until the rise time (for example for several seconds).
  • the tension is changed back to the specific yarn tension T2.
  • the unwinding assisting device 35 shown in FIG. 1 decreases in its effect, allowing a gradual increase in the unwinding tension.
  • the timing to find this 30-percent wound bobbin can be detected by the unit controller 11 which controls the lifting device 39 of the unwinding assisting device 35 in FIG. 1. Then, during the period from the time t6 to the time t7 bobbin change for changing the empty bobbin to a new one is performed; and unwinding is restarted with a slightly higher yarn tension T1 so that the yarn layer will not slough off, and then the yarn tension is set back to the specific yarn tension T2 at the time t8.
  • T1 slightly higher yarn tension
  • the winding speed is set lower than the specific value in order to prevent the yarn layer on the package from sloughing off.
  • the unwinding tension tends to increase during the period from the time t5 to the time t6 although the yarn tension is gradually decreased, it is possible to gradually decrease the winding speed also.
  • the specific unit is illustrated as to be a single unit. However, for example, plural units more than two units may be set to be the specific units which act for all units. In that case, the operation data which are obtained from a plurality of specific units are averaged and the operation condition of units other than the specific units may be possibly controlled based on the averaged data.
  • the yarn tension control device of the automatic winder functions to control the tensioning device of a multitude of spindles other than a specific spindle with reference to an output value to the tensioning device at the specific spindle to be feedback-controlled by for example the yarn tension detecting device, presenting the optimum tension pattern to a plurality of spindles for producing the same type of packages without using the yarn tension detecting device at every spindle and accordingly enabling high-speed winding while suppressing an increase in the yarn tension at the end of winding and decreasing yarn breakage at the end of winding.
  • winding can be performed without slough-off by setting a high additional tension value at the beginning of winding of the package and also by setting the winding speed lower than that for the package of normal size. Shown in FIG. 6 is this winding speed and tension control.
  • Described in the above-described embodiment is an example of controlling the tension to be stored in the control device 11 and the voltage value of the solenoid with the package in a wound state and with the bobbin in an unwound state.
  • various maps may be stored in accordance with the package winding speed.
  • the yarn tension may be changed in accordance with the winding speed; the voltage value may be set to various values; and the rise and fall gradients may be arbitrarily set.
